SPIKE-FULLER.

Specification Application filed June 22,

1"0 aZZ wit-0m it may concern:

Be it known that I, FREDERICK lVooncook, a citizen of the United States, residing, at Duanesburg, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in vSpike-Pullers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to certain new and useful improvements in a spike extractor or puller and has for its primary ob ject the provision of a spike extractor which may be specially adapted for removing spikes from car rails and the rail sections of a track with a minimum expenditure of time and labor.

The invention has for another object the provision of a spike extractor of the character stated which will be constructed in such a manner that it may be employed for extracting bolts which are difiicult to reach by other extracting means and which improved spike extractor will be of simple and efiicient construction and operation and composed of a minimum number of parts.

The invention has for a still further object the provision of a spike extractor of the character stated in which a supporting frame and base will be provided for the lever carrying the spike engaging and extracting member so that the lever may be readily supported at a distance from the spike to be extracted, thereby obtaining a proper leverage.

With the foregoing and other objects 1n view as will appear as the description proceeds the invention consists in the novel construction, combination and arrangement of cooperating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of the present application and in which:

Figure 1 is an elevation of the spike extractor.

Fig. 2 is a detail transverse section on the plane of line 2-2 of Fig. 1.

Fig. 3 is a longitudinal section on the plane of line 33 of Fig. 2.

Fig. 4 is a detail transverse section on the plane of line 4-4; of Fig. 1.

eferring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the of Letters Patent.

1920. Serial No. 390,704.

several views, 1 indicates the base member, upon the opposite side edges of which are secured the lower edges of the side plates 2 connected. at their upper edges by the transverse connecting member 3 preferably formed therewith, constituting the supporting frame for the lever and the connecting member 3 being cut away at its forward edge to permit of a further upward movement of the forward or working end of the lever 4, which is pivotally mounted upon the pivot pin 5 passing therethrough and through the side members 2 and held in position by suitable nuts 6 or the like mounted upon its threaded end.

The lever 4 has a flared rear end 7 with a central socket 8 formed therein, whereby an extension handle may be mounted upon the large rear end 7 in any suitable and well known manner. The forward end or working end of the lever, which end is designated by the numeral 8 has its opposite side portions flattened and is provided with a downwardly extended transverse slot 9 to receive the transverse bridge or arm 10 of the spike extractor pulling element adapted to be mounted on the end of the lever 4, as shown in the drawings. The body 10 of the spike extractor has the opposite leg portions 11 extended in parallel relation from its opposite ends with their main portions directed downwardly and then terminating in inwardly turned prongs 12 or fingers which extend toward one another and are slightly spaced apart for gripping engagement with opposite sides of the spike head. The upper ends of the legs 11 project slightly above the arm 10 to form a seat 18, for the free forwardly extended ends of the flat leaf spring 14 which projects over the slot 9 to retain the spike extractor in proper position upon the end 8 of the lever 4. It will be understood that the rear or remaining end of the flat leaf spring is secured upon the upper face of the lever at by suitable securing members 14. In use, the base 1 is positioned a suitable distance from the spike to be pulled or extracted, the rear end of the lever 4 raised and the spike extractor engaged with the head of the spike to be removed. A downward ressure on the rear end of the lever 4 will then result in swinging the lever upon the pivot member 5 and a raising of the forward end of the lever with the members 2 and 3 the spike to extract the same. It will be readily seen that, owing to the construction of this device, it may be readily employed in places where ordinary extracting members cannot be handled to advantage. For example, the device is especialy adapted for use in extracting or pulling spikes from guard rails and switch frogs of railway tracks.

While the preferred embodiment of the invention has beenshown and described, it will be understood that minor changes in the details of construction and arrangement of parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

What is claimed is 2-- An extractor of the class described havnotch disposed intermediate said walls and on the lever, an extractor member having a bar disposed in said notch, the side walls of said notch diverging from the base to the entrance, said spring en 'aging said extractor member .to normally maintain it spaced with respect to said walls, and retaining means for the springs on said arms.

In testimony whereof I affix my signature in presence of two witnesses.
